TALKING SHOP WITH REFINERY29

Our co-founders Marissa and Lauren know a thing or two about bras - what you should own and why you should own it. We teamed up with Refinery29 to go through the basics to outline some intimate advice on intimate apparel - from T-Shirt bras to Balconettes to Bralettes and Bandeaus - we've got the expertise you need to know.

And of course, when it comes to invisibility and comfort, we've also got you covered - with our White Boa Demi Bra featured as one of the T-shirt Bras you shouldn't live without (!)

"The T-shirt bra is really any style of bra that has a seamless, smooth look under a fitted shirt," say Negative cofounders Marissa Vosper and Lauren Schwab. "Bells and whistles get in the way of the intent of the bra. Think smooth cotton, lycra, nylon, and silk — lace generally doesn’t cut it here."

The rub? T-shirt bras are often totally boring, which is why we made ours in a super sexy white out snake print - engineered to feel awesome under clothes, but even better without any on :)

Wrap a tape measure around your ribcage, following the base of your bra band - pull taut so there's no dip in the tape, but not so tight that you create an indent. This number, in inches, is your band measurement. If the number is odd, round up to the nearest even.

Step 3: Bust Measurement

Move the tape around the fullest part of your bust, typically at the center of your nips, wrap evenly around your back, holding taut without any dipping. Take this measurement in inches, this is your bust measurement.

Step 4: Bra Size

Take your bust measurement (second one) and subtract your band measurement (first one). Each inch difference between your band and bust measurements equals one cup size. The band measurement and cup size combined are your underwire bra size.
